There is no "New and Noteworthy"
specifically for RC1, since we are in the phase of "bug fixes only",
but if you haven't read them yet, you can start with the New
and Noteworthy for M7, which also
has links to the previous ones for Milestones of the Mars Release (by our
Release we will, of course, consolidate them into one document).
But we hope that everyone can immediately
download and begins "final testing" of our Mar's deliverables.
Not much time left, to fix any major bugs or regressions you find -- so,
the earlier the better!
